Optoma ZH521ST

Compact High-Brightness Short Throw Laser Projector

The Optoma ZH521ST is a powerful Full HD short throw laser projector designed for business, education, golf simulation and commercial environments. Delivering an impressive 5,300 lumens of brightness, it produces large, vibrant images from a short distance while reducing shadows and installation constraints.

Short Throw for Maximum Impact

The dedicated short throw lens projects large, clear images even in smaller rooms, making it ideal for classrooms, meeting rooms, golf simulators and interactive presentation spaces where the projector needs to be positioned close to the screen.

Long-Life DuraCore Laser Technology

Powered by Optoma’s DuraCore laser light source, the ZH521ST delivers up to 30,000 hours of maintenance-free operation. Instant on/off performance, consistent brightness and reduced energy consumption help lower the total cost of ownership.
